LZ你好
本人不知道你这个是什么页面,其实程序里面可以用变量和控件来获取值,不需要完全用SQL语句,原因是SQL语句太多,执行效率太低,以下仅供参考
SELECT CONCAT(region_name,store_name) FROM Geography
订单消息
select send_date,concat(select member_name from member where member_id=member.member_id,”下单”),concat(“订单号”,id) from rr_notification_info
活动消息
select message from rr_notification_info
系统消息
select convert(varchar(100), getdate(), 5),message from rr_notification_info
